The Turks have a mountain of injury and suspension problems ahead of their match with the highly-fancied Germans, but their never-say-die attitude makes them dangerous opponents.

"Turkey are certainly not better than us tactically, technically and in terms of individual players," said the Chelsea midfielder, who excelled in Germany's 3-2 win over Portugal in the last eight. "But they are unpredictable and they won't underestimate any of us."

He added: "Turkey have up until now always been brilliantly set up against their opponents and they almost have a bit of the German mentality about them.

"It will be a tough task, but we have a big chance of making the final."

Ballack is set to have Torsten Frings back alongside him in centre midfield at St Jakob Park, the Werder Bremen anchorman having returned to training after breaking ribs.

Indeed, Germany coach Joachim Low confirmed all 23 players in his squad were available for the match.

The situation is the exact opposite for Turkey coach Fatih Terim, who could be faced with the prospect of playing third-choice goalkeeper Tolga Zengin in an outfield position if he is needed off the bench.

The latest blow to befall the Turks came on Monday when UEFA turned down goalkeeper Volkan Demirel's appeal against his two-game suspension.

Volkan, Terim's number one stopper, was sent off in stoppage time of his side's dramatic 3-2 Group A victory over Czech Republic after pushing Jan Koller, and missed the quarter-final win over Croatia as a result. He had hoped to get the ban reduced in order to play against Germany, but UEFA have upheld their decision.
